LEVELING ATTACHMENT.

Application filed June 24,

To all whom it may concern:

Be it known that I, Hnnenn'r F. U NRUH, a citizen of the United States,residing at Meno, in the county of Major, State of Oklahoma, haveinvented certain new and useful Improvements in Leveling Attach ments;and 1 do hereby declare the following to be a full, clear, and exactdescrip tion of the invention, such as will enable others skilled in theart to which it appen tains to make and use the same.

This invention relates to new and useful improvements in agriculturalmachines and particularly to attachments therefor.

The principal object of the present in vention is to provide a novelandimproved attachment for a cultivator which will break up the ridgesand level the same.

Another ob ect is to provide a novel and improved device of thischaracter which is capable of being applied to any cultivator now inuse.

A further object is to provide a novel and improved attachment of thischaracter which can be readily and easily adjusted to different angles.and which can be raised and lowered as desired.

Other objects and advantages will be up parent from the followingdescription when taken in connection with the accon'ipunying drawing.

In the drawing:

Fi ure 1 is a top plan view of a cultivator showing the attachmentthereon.

Fig. 2 is aside elevation of the same.

Fig. 3 is a rear elevation of the same.

Fig. 4 is an enlarged detail view of the bracket A removed from themachine.

Fig. 5 is anenlarged vertical longitudinal sectional view taken on theline 5-5 of Fig. 1.

Referring particularly to the accompanying drawings, 10 represents theframe of a cultivator to which are secured a transverse beam 11 carryingthe cultivator disks 12. A bracket is secured on each side of the frameof the cultivator and extends rearwardly therefrom. Each of thesebrackets is formed from a single length of metal of suitable width andthickness for the purpose. and includes an open triangular body A whichis bolted to the frame of the cul- Specification of Letters I'atcnt.

tivator and may inclose cross bars therein if any exist, the rearwardlyextending portions or arms 14, and the circular portion 15 whichconnects the rear ends of the arms 14, and receives therein one endportion of a transverse shaft 16. This shaft is ar ranged to rock in thesaid circular portrons, said portions acting as bearings, and secured tothe central portion of the shaft and rising therefrom, is an arm 17which is connected to an operating lever 18 mounted on the frame of theinai-hine. A coil spring 20 is connected at one end to the frame of thecultivator and at its other end to the said arms 17 for assisting inswinging the lever to rock the shaft. Secured to the shaft at oppositesides of the arm 17, and extending rearwardly therefrom, are trailingarms 21 adjustable longitudinally on the said shaft by set screws 22.The rear ends of the arms 2'! are connected to other arms 23 by means ofball and socket joints Bi and set screws whereby each second arm iscapable of being adjusted to dilferent angles with rcspcct to the firstarm and to the ground. Carried by the rear ends of the arms 23 areground treating disks 2?, the same being adjustable to different angleson said arms for action on the soil to dii" i'erent angles and depths.

This attachment serves as an efficient means for breaking up andleveling the soil of the ridges in which were planted the crops of theprevious year. Ordinarily, when plowing, these ridges, though broken bythe disks of the plow, remain in ridges, or humps, higher than theremaining portions of the soil. The rear disks 25 eflcw tively break upthe ridges and spread the soil therefrom evenly and properly so thatwhen the field is plowed it will have a level appearance.

The device is of such nature that it may readily be attached to anyultivator without modifications to the cultivator or plow.

What is claimed is:

A ridge leveling attachmcnt for an agricultural machine, the samecomprising a pair of brackets whereof each includes an open triangularbody for attachment to the frame of such machine, arms projectingrearwardly from the body, and bearings carried by .suid arms, :1 l'0lfI(Shil1 l] ournaled trailing arms whereby their au'lgles therein in saidbearings, an arm rising therefrom, ma be adjusted 10 a lever connectedby a link with said arms n testimony whereof, I mfix my signaforadjusting the position 01 the shaft, fl'ililbum, in the presence of twoWitnesses.
